JOHN PEARD, OF BROOKLYN, NEW YORK.

E VAPORATOR FOR HOT-AIR REGISTERS.

SPECIFICATION forming part of Letters Patent No. 247,682, dated September 27, 1881.

Application filed February 25, 1881. (No model.)

To all whom it may concern:

Be it known that I, JOHN PEARD, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented new and useful Improvements in Evaporators for Hot-Air Registers, of which the following is a specilication.

My invention relates to that class of detlectors which are provided with water-tanks and arranged over hot-air registers for the purpose ot' moistening the hot air prior to its escape into the apartment to be warmed.

The object of my invention is to provide simple and inexpensive devices for this purpose, and to provide them with water-tanks which can be supplied with water from the exterior ot' the deiector, as required, without disturbing or removing the delieotor.

This invention is illustrated in the accompanying drawings, in which, Figure 1 represents a horizontal section in the plane 1/ y, Fig. 2. Fig. 2 is a vertical section in the plane ma, Fig. 1.` Fig. 3 is a horizontal section in the plane z z, Fig. 2. Fig. 4 is a perspective View on a smaller scale than the previous figures.

Similar letters indicate corresponding parts.

In the drawings, the letter A designates my deector, which is by preference made of sheet metal, but which can be made ot' any suitable material.w It is open at the bottom and made with an inclined top, a, a Hat front, b, and two side Ilanges, c c, and ot' such a size that its inner edges fit closely against the wall which contaius the hot-air register B, or against the frame of said register.

In the example shown in the drawings my detlector is provided with legs d d, so that it can be placed over the register, as shown in Fig. 2; but the deector may be made without legs, and secured to the frame ot' the register by means 0f screwsl or other suitable fastenings.

ln the interior ot' the vdetlector are secured two tanks, C C, which are intended to be filled with water. These tanks extend through the side tlan ges, o c, of the detlector, so that they can be conveniently supplied with Water without removing the detlector from lthe register.

It desired, only one tank, C, can be used, and

this tank is placed at a slight distance from the front b of the detlector, so that the hot air which escapes from the register, on coming in contact with the inclined top a, is deflected down and brought in contact with the water in said tank before it escapes at the open bottom end of the delector, and thereby said air becomes charged with a sufficient quantity of moisture to deprive it of its noxious effects on the health of the persons occupying the room.

It' the tanks C C are used, both may be placed at adistance from the front of the detlector, so as to allow the heated air to circulate all round to the front b as shown in Figs. 2 and 3, and in this case I provide openings e in the front b through which the heated and moistened air escapes.

My detlector is lapplicable to registers of {ireplace heaters, or to registers of air-heaters situated in the cellar of a building and communicating with registers fitted into the walls of the dii'erent rooms.

It is obvious that the number of tanks in the delector can be increased, itl desired.

By reference to Fig. 2 itwill be seen that the lever for operatin g the valves ot' the register' is situated beneath the tank C in the detlector, so that the register can be opened or closed without difficulty.

Vhat l claim as new, and desire to secure by Letters Patent, is-

1. The deeetor A for hot-nir registers, con structed with an open bottom, tiat front b, side flanges, c c, and the upper inclined end, (t,join ing and forming a continuation of the iiat front b, in combination with the horizontal watertank having its ends held and supported solely by the side ianges, c, ot' thc deiector to provide a clear open bottom to the latter for the free downward passage and escape ot' the vaporized hot air, substantially as shown and described.

2. The deect-or A for hot-air registers, consisting of a front b, top c, and vertical sides c, in combination with a water-tank supported by the sides, the said water tank extending through one or both of the sides c, to provide for supplying the same with water from the exterior ot the detlector, substantially as deA scribed.

In testimony whereof I have hereunto set my hand and seal in the presence of two subscribing witnesses.
